Exploring Bouncing Balls
Source Institutions
Learners explore the physical properties of a variety of balls and how they bounce.

Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

Built in Stopwatch
Source Institutions
In this activity (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

Super Spinners
Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Lifting Lemon
Source Institutions
In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

Stroboscope
Source Institutions
In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.

Home Mycology Lab
Source Institutions
Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.

Underwater Hide and Seek
Source Institutions
In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

Onion DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

Bonseki Salt Art
Source Institutions
In this activity learners will be creating art using a traditional Japanese art style.

Magical Match
Source Institutions
In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

Gluep
Source Institutions
In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.
